For manufacturers developing competitive devices that are easy to install and maintain, the Wireless M‑Bus Protocol Stack from STACKFORCE is the ideal foundation. With low power consumption, a modular architecture and a rich set of functionalities, the stack supports a broad range of Smart Metering, Sub‑Metering and Smart City applications.
In this article, you will learn more about its features, implemented standards and available stack options.
Stack Features of Wireless M-Bus Protocol Stack
The Wireless M‑Bus Stack implements seven protocol layers and provides flexible interfaces to meet various integration requirements:
- Application Layer API: Designed for single‑chip solutions
- Security API: Optional externalized security handling
- Hardware Abstraction Layer (HAL): For cross‑platform support
- Serial Interfaces (UART, SPI, etc.): All APIs available with minimal overhead
For security‑critical applications, the stack supports AES encryption and other secure communication mechanisms.
Operating Modes & Flexibility
The stack offers extensive configuration options to adapt to different device types and use cases:
- Modes S, T and C: Selectable depending on application needs
- Unidirectional / Bidirectional communication: Adjustable at runtime or compile time
- Synchronous intervals: Includes hardware timer compensation and automated packet handling
It supports all common non‑volatile memory types (EEPROM, Flash, MRAM) and allows platform‑specific optimizations such as AES, CRC‑16 or Manchester / 3‑out‑of‑6 coding.
Implemented Standards
The Wireless M‑Bus Stack covers the majority of options and features defined in the key European metering standards:
- EN 13757‑3 / ‑4 / ‑7: Core foundation for wireless metering communication
- OMS Specification Version 4.2.1: Fully supported
- OMS Version 4.3.3: In development (planned release: Q2/2022)
Additional sub‑standards can be supported upon request, including DSMR, ESMR, or CIG UNI/TS 11291‑11‑4 PM1.
Using the OMS specification ensures cross‑vendor interoperability, simplifies network deployment and allows the use of additional frequency bands for international applications.
Das Wireless M-Bus Stack Package
Each stack package includes everything required for fast, reliable integration:
- Precompiled stack library
- Hardware‑specific drivers
- Serial interface & power‑management components
- Example app folder for integration into custom firmware
- Modem app folder for two‑chip designs
Single‑Chip or Two‑Chip Operation
- Single‑Chip Design: Stack library integrated directly into the application
- Two‑Chip Design: Modem app creates dedicated communication firmware; host system accesses the protocol stack externally
Access Included in the License
- Protocol Stack: Object code
- RF drivers: Object code
- HAL: Source code
- 12 months maintenance included; additional support available depending on the license model
The Wireless M‑Bus Protocol Stack is designed for maximum flexibility, efficient communication and long‑term reliability—making it a strong foundation for metering and IoT devices of all kinds.
